I was diagnosed with Lyme of April '08 and was on treatment of doxy for about 1 month and a half. After treatment I had joint pain and weakness for a while, and it eventually went away for the most part. It would only coming around occasionally when I did strenuous activities, like my summer job of waiting tables. Since September '08 I have been fine, with no symptoms at all. Starting last Friday I felt pretty weak, and it is still hanging around today. I feel flu like with aches, and with a little joint aches as well,but I have no temperature, so I do not think it is a flu. My question is could a flare up happen that long after treatment and that long after such an extended period of feeling fine? I do not think I got reinfected either, because I used to live in PA where Lyme disease was very prevalent, but now for the summer I have lived in an area of the country where ticks carrying Lyme is not common at all. I'm planning on seeing the doctor soon, I'm just curious what you guys think.
